摘要
焦化废水主要来自焦化厂和煤气厂,污染物组成复杂,含有挥发酚、许多难以生物降解的芳香族有机物、多环化合物和氧硫氮等杂环化合物,属较难生化降解的高浓度有机工业废水。因此焦化废水的处理难度大,已引起国内外人士的关注,一直是国内外废水处理领域的一大难题。文章阐述了焦化废水的处理技术发展及其近年来发展的新技术。
The cokingw astewater is produced in coking plant and gaswoks ,which is abundant in hydroxybenzene and difficult to dispose ,contains wide range of contaminants ,including non -biodegradable multicomponent or ganics ,heteroaromatic compound .Therefore ,the dispose of the coking wastewater is still a problem in the wastewatertreatment.The development and achievements of coking wastewate were expounded comprehensively .
